Given a numerator \f$ a\f$ and a denominator \f$ b\f$ this `AdaptableFunctor`
|
|
scales a `PolynomialTraits_d::Polynomial_d` \f$ p\f$ with respect to one variable,
|
|
that is, it computes \f$ b^{degree(p)}\cdot p(a/b\cdot x)\f$.
|
|
|
|
Note that this functor operates on the polynomial in the univariate view, that is,
|
|
the polynomial is considered as a univariate homogeneous polynomial in one specific variable.
